Letters Patent No. 108,589, dated October 25, 1870.

IMPROVEMENT IN C ARPET-BEATERS.

The Schedule referred tc in these Letters Patent and marking part of the saine.

To Il whom'it may concern.:

Beit known that I, WrLLLur 1H. Hanni-uson, ot` the city, county, and State of New York, have invented a rrewland vimproved Carpet-Renter; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to Ina-ke and usepthc same, reference being had to the accompanying drawing, forining part of this specication, in which- Figure l represents an end elevation of my im# proved carpet-beater.

Figure 2 is a side elevation, partly in section, of the same.

Figure 3 is avertical transverse section of the same, taken on the plaire of the line :c a', fig. 2.'

Similar' letters of reference indica-te corresponding parts. K

This inventionrelates to an improved machine forlbeating and cleaning carpets and other fabrics; ant

It consists in the combination and arrangement of beaters, springs, toothed disk, and brush and rockshat'ts, and lmore particularlyin the arrangementof a set of double-acting springs, by which the strokes of the beaters are made elastic, and properly yielding. The carpet is thereby prevented from injury during the beating" process.

A in the drawing represents' the' stationary frame of my improved carpet-beater.

This frame is made of wood, or other suitable material, and'ot' such suitable size and strength as adapts it best to the support of thernachinery used.

B C are the two beater-shafts, hung in the frame, and provided with wire beaters D D. l

These beaters are secured,totheirshaits by means of clasps a o, or in other suitablemanner, and have coils b l), or other nica-ns of becoming elastic.

The shafts B C are 4hung parallel to each other, and carry projecting cranks c c at their inner ends,

which cranks, when struck by projecting pins (l, on a -revolvingdisk, e,'c ause the shafts B C to be swung,

so. that .the beatersfare ycarried apart.

The disk c is mounted upon a horizontal drivingsliaft, E, which receives rotary motion by suitable mechanism.

The pins d are fitted through slotsv in the 'disk c, and clamped by nuts j, being thus made adjustable to refrulate the strokes of the beaters,

Thbe outer ends of the shafts-B G carrycranks g g,

which are, by strong springs h 7i, connected with a cross-bar, t, Aot the frame A.

When the shafts B C are swung, by means of the y pins (I, the springs 71 are stretched, and will, as soon as the pins (l leave the cranks c, rapidly contract,

so as to swing the shafts back, andpowerfullyvt'force the beaters against the carpet suspended between beaters, tending to draw them oi the carpet. at the l moment ot the stroke, and prevent thereby the injuring ot' lthe carpet bythe violence of the strokes.

FF arc rotary brushes, arranged above or below the beaters on opposite sides of the carpet, and connected with the driving-shaft by suitable lde-l vices. They serve to remove the dust laid loose by the beaters.

l The carpet is hung upon suitable rollers, G H,

which are revolved to gradually move it along between the beaters. n It is evident that the springs used in connection Awith the rock-shafts B C, may be made spiral, flat,

or of other suitable form, ot' metal, rubber, or other material.

A case, I, may bcused to envelope the beating and brushing machiner ,and to keep the dust from flying about.

Having thus described my invention, A

I claim asnew and desire' to secure lby Letters Patent- 1. .The combination, in a carpet-beater, of the adjustable wire beaters I) D, rock-shafts B O, cranks c, disk c, pins d, springs 71 and .,7', cranks g, and 'brushshaft F, all arranged substantially as shown and described.

2; The springs 71, combined with the cranks g and compensating springs j, for the purpose -oi actuating the carpet-beaters, substantially in the manner herein shown and describetk WILLIAM H. HANKINSON.
